this paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. in fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. thepower output of each hydro unit varies with the rate of water discha...

Turbine is the most critical component in hydropower plants because it affects the cost as well as overall performance of the plant. Hence, for the cost effective design of any hydropower project, it is very important to predict the hydraulic behavior and efficiency of hydro turbines before they are put in actual use. Experimental approach of predicting the performance of hydro turbine is costl...

OBJECTIVES The objective of this study was to analyze the fatty acid content, antioxidant, and antibacterial activities of hydro-methanolic extract of Adonis wolgensis L. (A. wolgensis L.) growing wild in north of Iran. MATERIALS AND METHODS Oils of A. wolgensis L. was obtained by means of Soxhlet apparatus from leaves and stems. Methyl esters were derived from the oily mixtures by trans-este...

saymareh dam and hydro-power plant are under construction on saymareh river in ravandi anticline, ilam province. during boring the power tunnel which crosses the anticline, a large volume of water was encountered. this volume of water was not observed in the past. considering the water quality of springs, water level of dam site piezometers, geological and hydrogeological inspections, isotope a...
